Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Downloading Software And Replacing The Control Module
It is possible to download software to the FSM. It is also possible to download software separately to the FLR.
When replacing the windscreen or FSM, the camera unit must be calibrated using the diagnostic tool. This must also take place when downloading software for control module in case fault code FSM-500154 is set.
From structure week 201020 only the Forward Looking Radar (FLR) needs to be calibrated when only the radar has been replaced or only software for the Forward Looking Radar (FLR) has been downloaded.
When the FLR is replaced and/or software is downloaded to the FLR, only the radar needs calibrating.
When ordering software the vehicle's hardware and software are compared with Volvo's central database. If the comparison is correct the software is downloaded to the control module.
If the comparison between the car and Volvo's central database does not correspond, then the database is updated with the vehicle's configuration. When this is complete the software is downloaded.
